major power loss 1.9TDI 130

A FRIEND FONED ABOUT A POWER LOSS ON A 2003 1.9TDI 130 IN ALL GEARS BELLOW 2200 REVS OR SO, SO I HEADED DOWN AND STUCK THE GOOD OLD VAG-COM ON IT, PULLED UP MAF AND BOOST PRESSURE COMPENSATION. SO I CHANGED THE MAF SENSOR AND CLEARED THE FAULT CODES, STILL TO FIND THE POWER LOSS WAS THEIR AND REALLY BAD, AND NO FAULT CODES BEING READ NOW. RELATING TO THE BOOST PRESSURE COMPENSATION I THOUGHT ID CHANGE OVER THE BOOST PRESSURE SENSOR FROM MY OWN CAR (SAME CAR) STILL TO FIND NO DIFFERENCE!

THEIR IS NO BLACK SMOKE POORING OUT OF THE BACK SO ITS REALY GOT ME.

THEIR WAS ALSO FAULTY BRAKE SWITCH SO I CHANGED IT FOR ONE LAST STAB BUT NOTHING

ANY1 EXPERIENCED ANYTHING LIKE THIS OR SHED ANY LIGHT ON SUMFING ELSE TO CHECK.
